1 Claim. (o1. 13)

This invention relates to foldable bed and sofa combinations and inparticular to one in which the foldable structure of the bed may bedetached from the frame of the sofa or chair.

An important object of the invention is to provide, in a device of thecharacter referred to, means whereby the foldable bed frame may bereadily and quickly detached from the inner surfaces of a sofa or setteeframe into which it is folded to provide a sofa unit, so that theotherwise cumbersome combination may be quickly separated into itscomponent parts for easy movement through a door or restricted passage.

A further object of the invention is to provide a connecting meanswhereby the bed frame can be fitted into the chair frame without anyadjustment of parts; can be secured therein against accidentaldetachment when the complete article of furniture is lifted; can bedetached and attached without the need of tools and by a woman withoutthe need of excessive manual effort; and one in which the parts are ofsimple construction so that in manufacture, the bed and chair frames canbe quickly and easily assembled.

With these and other objects in view, the invention comprises certainconstructions hereinafter described and then particularly pointed out inthe claim and a preferred embodiment of my invention is illustrated inthe accompanying drawing, in which:

Figure 1 is a view in longitudinal section of a combination sofa and bedstructure showing the latter in open or extended position andillustrating-the relative location of the fastening means,

Figure 2 is an enlarged section taken on the line 22 of Figure 1,

Figure 3 is a side view of the fastening means shown in Figure 2,

Figure 4 is a side view of the fastening means used adjacent the frontof the sofa frame, and

Figure 5 is a section taken on the line 55 of Figure 1.

Referring to the drawing in detail, In indicates generally a folding bedand sofa combination, the parts of which, heretofore, have beenpermanently fastened together by the usual screws or bolts requiring theuse of tools for assembly or separation of said parts. The bed frame I Icomprises relatively foldable parts including inner sections l2 and I3which are mounted within the frame it of the sofa into which the outersections of the frame fold in the well known manner.

In order to detachably mount the bed frame I I in the sofa frame l4 useis made of front and rear detachable connecting means It and I6, re-

spectively, which are located at the sides of the frame II and areconnected to suitable adjacent parts of the frame Id. The bed frameinner sections I2 and I3 are of angle iron construction and to thelatter, adjacent the opposite inner corners of the frames II and I4,there is secured as by the rivets Il, vertical links I8 each havingfixed in the upper end thereof a latch'pin I9 presenting an extendedshank 20 and a head 2| at the outer extremity thereof. Each pin and linkconstitutes a hanger for the inner corner of the bed structure, the pinI9 being adapted for detachable engagement with a downwardly andoutwardly directed bayonet slot 22 formed in the lower end of a supportarm 23 secured as by screws 24 to an inner surface of the sofa frame I4.

The latch pin [9 is self seating in the bayonet slot and protrudesbeyond the surface of the support arm 23 so that it can be seated in theslot 25 of a latch 26 which is pivoted at 21 for swinging movement onthe arm 23. For convenience of manual operation, the latch is providedwith a finger pin 28 at the outer extremity thereof so that it can bereadily and easily swung to latching or unlatching position. The head 2|of latch pin i9 is greater in diameter than the width of the slot 25 ofthe latch so that sidewise sway of the inner end of the bed structure isprevented and accidental detachment of the pinand latch in lateraldirection is avoided.

As shown in Figures 4 and 5, the section I2 of the frame I I issupported at opposite sides on the upper end of a lever 29 which ispivoted as at 30 to a side plate 3| secured in any suitable manner tothe inside of the sofa frame It and yieldably biased to verticallyoblique position by a spring 3IA. The upper end of the lever 29 isprovided with a latch pin 32 suitably riveted in the lever andpresenting an extended shank portion 33 and a head 3 spaced from saidlever. The pin 32 is I adapted to seat in a bayonet slot 35 formed inthe vertical wall of the angle iron frame section I2 and whose closedend is directed rearwardly so that the pin 32 is embraced by oppositeedges of the slot and prevented from accidental detachment. The pin 32is locked in the inner closed end of the slot 35 by a latch 36 having aslot 37 for embracing the pin 32 when the latch 36 is swung down tolocking position about its pivotal attachment 38 to said frame section12. For convenience of operation, the latch 36 is provided with a fingerpin 39 so that it can be manipulated with a minimum of effort. The head34 of the pin, in this instance, is also of greater diameter 3 than thewidth of the slot 31 so that maximum stability of the bed frame isafforded.

It is evident that I have provided a novel detaching means for use inholding the parts of a combination sofa and bed structure in separablerelation and one that can be readily and easily manipulated with aminimum of effort so that the separated parts of the furniture can bemore conveniently handled and so that in manufacture, bed and sofaframes can be rendered interchangeable, if desired. The use of the termssofa and settee may include such articles as tables and single armchairs in which foldable bed structures may be incorporated.

My invention is not to be restricted to the precise details ofconstruction shown since various changes and modifications may be madetherein without departing from the scope of the invention or sacrificingthe advantages to be derived from its use.

What I claim is:

In furniture adapted for alternate use as a bed and a sofa, thecombination with a sofa frame and a sectional bed frame foldable intosaid sofa frame; of a vertical link attached to the bed frame atopposite inner corners thereof, a downwardly and outwardly extendingsupport arm in each inner corner of the sofa frame shaped to provide anobliquely disposed slot having an offset portion therein, a latch pin onthe vertical link for self seating reception in said slot for pivotalsuspension of the inner section of the bed frame from said sofa frame,said latch pin being shaped to provide a shouldered portion for holdingthe support arm and link in contact relation whereby lateral swayingmovement of the bed frame with respect to the sofa frame is prevented, alever, means for mounting the lever on the sofa frame, a pin in the freeend of the lever for engagement with a rearwardly extending angular slotin a section of the bed frame, a latch on said section having a slot forengagement with the pin for holding the latter in the closed end of saidangular slot, and a finger projection on said latch.
